A third Idaho appellation was federally
authorization as of May 2016.
The 306,658 acres
within this new AVA are now officially the
Lewis-Clark Valley AVA
shared by Idaho and Washington State.
About 72% (219,838 acres)
is located in Idaho, the rest in Washington.
It include parts of
seven counties in the two states and is centered around a
40-mile-long strip of canyons, low plateaus and bench lands formed
by the Snake and Clearwater Rivers with the cities of Lewiston,
Clarkston, Washington nearby.
These two towns face each other across
the Snake River and were named in honor of Meriwether Lewis and
William Clark who traveled through the region of this AVA
during their famous expedition of 1803 - 1806. Nestled in a
unique mountainous region of the Bitterroot Mountains - the
backbone of northern Idaho,
the area was a premier wine-grape growing
area in the early 20th Century, but that disappeared after
Prohibition. Evidence of the area’s former winemaking
history, including hundreds of acres of abandoned vineyards, can be
found throughout the region. In the early 2000s, wine grapes started
to make a comeback in the area, and today's Lewis-Clark Valley AVA now (as
of September 2016) includes
five wineries, 16 grape growers and 81 acres of wine grapes.

Idaho & Washington's Lewis-Clark Valley AVA:
ACREAGE - Formed by the
Snake and Clearwater rivers, the Lewis-Clark Valley AVA consists
of canyon side and bench lands and is 306,658 acres in size.
About 72% (219,838 acres) are located in Idaho, the rest in
SOIL - Mollisols soils comprised primarily of decomposed perennial grasses
and grass roots with high water holding capacity. The majority of
soils contain loess, or wind-deposited nutrient-rich silt.
GEOLOGY - The geology of the
AVA creates good planting areas that are easy to develop and
contain air drainage characteristics ideal for wine grapes.
It also contains steep sides with shallow stony surficial cover
for more classic and exotic vineyards sites. This AVA is
home to the lowest elevation vineyards in the state of
Known as the “banana belt,” the
Lewis-Clark Valley is known to be a temperate climate within the
colder surrounding regions--this produces high quality fruit trees
such as peaches, apples, wine and table grapes. Steep v-shaped
valleys allow for good air drainage, providing frost protection and
cool nighttime temperatures for acid retention and flavor
development. The annual precipitation varies between 11-22” each
year with 2600-3000 average annual growing degree days.
Directly below originating water sheds of the Palouse and Camas
Prairies. Annual precipitation is sufficient in some areas to
allow for minimal irrigation.
VARIETIES - Twenty-three grape varieties are currently
(as of April 2016) grown and sold in the vineyards of the
AVA - 14 red wine grapes and nine white.
Vines were planted in the Lewis-Clark Valley as early as
1872. Varieties such as Petit Syrah, Petit Verdot and
Cabernet Franc were cultivated. By 1908, 40 varieties
of grapes were being cultivated. Two years later,
Lewiston voted a ban on alcoholic beverages and the industry
crashed. Most of the wine was turned into vinegar and
winemaking virtually disappeared until the late 1990s.
